Wa Bill Of Sale

The title is electronic, so I can not sign more. I also need to send a statement of responsibility, but who does go, CA or WA?

the state where the sale takes place, most likely, or many people would be running all over the world for sales invoices

My brother lives in San Diego and bought a car in WA. he had trouble doing that worked. he had to call AC. DMV and WA. DMV to get things right. I call the two states and ask to speak to people each time the same for each State
